Centrifuges are used for separating solid particles from the fluid of different density, for example for cleaning oil in drilling waste fluids. High rotation speed of the rotor creates large centrifugal forces, pulling heavier particles to the side of the rotor, where they stay until removed during a regular maintenance, or from where they are removed continuously by a special mechanism. Frequently, the rotor of the centrifuge is driven by a separate electric motor, or by a shaft from the car engine.

GN Solids Control, with a separate U.S. brand GN Solids America, is a professional manufacturer on different size of decanter centrifuges. The centrifuge size varies from 9 inch to big bowl 30 inch to meet the application of different field.
GN design and make both 2-phase decanter centrifuge and 3-phase centrifuge for industry separation.
What is a 2-phase separation decanter centrifuge?
2-phase separation decanter centrifuge can used to separate solids or soil from the solids liquid mixture. The final products are solids and liquid mixture. If the clients want to get separate oil and water, they will use an oil water separator after it.
What is a 3-phase separation centrifuge?
3-phase separation centrifuge is widely used for oil water separate. They can separate and get the 3 phase final products: oil, water and soil. For a better separation result, 3-phase centrifuge cannot allow high solids content. Normally it will be used after a decanter centrifuge. A 2-phase centrifuge will be used to reduce the mud weight first. And then the liquids transfer 3-phase centrifuge.
GN Solids Control makes and designs centrifuges per the specified tasks and application requirement. All material of GN brand centrifuges are only chosen from high standard and famous brands. GN Solids Control own the full line advanced centrifuge processing machines. All these ensure GN made centrifuges are with optimized performance.
Moreover, GN owns a branch for design PLC and electrical control system; this gives GN advantages in electrical components for measuring and control technology. The performance and availability of the decanter centrifuge or three-phase centrifuges are significantly improved by the control system.

Oil based mud is the most normal lubrication agent of offshore drilling rigs. During drilling activities, huge quality of oil base mud and oil based cuttings will be generated and come out together with the oil rigs. The sands and rocks come out together with the lubrication oil based mud will be covered with oily material, and it is Non hydrophilic. These oil base mud and oil based cuttings are hazardous and have very bad damage to the ground and environment. In order to reduce and avoid the oil base mud and oil based cuttings pollute environment, there should be a technology to inject the hazardous oil based mud and oil based cuttings to the suitable lay of the ground.
We call the technology of injecting hazardous oil based mud and oil based cuttings generated during drilling activities as drilling cuttings re-injection.

The environmental protection policy is more and more strict, The new policy regarding the zero discharge of offshore drilling in China marine area will come out very soon. The policy will bring new challenges to the drilling activities of offshore, so the drilling cuttings re-injection technology is imperative and necessary, especially in the Bohai area, drilling cuttings re-injection operation will be a must-be part of the drilling operation.
The drilling cuttings re-injection technology has been effective for many years in many countries, it is a mature technology rather than new.And it is proved that the drilling cuttings re-injection technology will not pollute the formation. As the injection ground layer is not a production layer, and it cannot break the cover to cause water pollution, and so on. The drilling cuttings re-injection technology is the most reasonable drilling waste disposal methods for remote offshore drilling rigs.
The core of the drilling cuttings re-injection technology m lies in the choice of the injection ground layer, to build the simulation of the joint and the system on the platform.

There are many different kinds of replacement shaker screens according to different shapes of the screen frame and material. Below is the most normal type shaker screen type we normally used:
1)    Hook type (hard hook) replacement screen. It is mainly for below type of shaker models:
Derrick 513 and 514 shaker and mud cleaner, Derrick 2000 or 48-30 shale shaker or mud cleaner.
2)    Frame type replacement screens. The frame screen is mainly for GN brand shale shaker and mud cleaner, Mongoose type shale shaker and mud cleaners, Cobra, King Cobra series shale shaker and mud cleaner. VSM-300 series shale shakers.
3)    Soft hook screen. It is a very old type screen model. Fewer shakers utilize the screen type. As the soft hook screen cannot last long time. Its quality is not good. But as its lower price, may some old shaker type still use it.

Tell from the materials, there are 2 types of frame screen: steel frame and composite material replacement screen.
Compared with steel frame screen, composite material screen can lost for a longer time, and it can be stocked for a longer time. Normally, the steel frame screen can only stock 1 or 2 years. If it stocks a longer time, the screen quality can be reduced, as the steel material cannot last long time even with suitable warehouse protection. But the composite material can last a longer time. You can stock the composite material for 4 or 5 years, if you do not need to use them. The reason is as the special design of the composite material screen. Inside of the composite screen, it is steel frame for reinforce. And then a special kind of plastic material to cover and fill the steel frame. As its complex production, the composite material price is higher than steel frame, but it can last a longer time.
GN Solids Control is a professional manufacturer for different models and type replacement screens. Welcome you contact GN group for more information of replacement shaker screen model.

The full 1500hp mud cleaning system is composed of below items:

1500hp rig mud system

1)    1 ea mud gas separator (poor boy degasser) before the mud system. It is used to cut the intrusive gas in the mud before shale shaker.
2)    The 1500hp mud system is composed of 3 ea linear motion shale shaker for pre-separation. It is the first stage separation.
3)    After the 3 shale shakers, there is a vacuum degasser used to cut the fine gas bubble and protection the hydro cyclone separators. As the hydro cycone is a kind of pressure device. The gas bubble may make damage to the cones.
4)    A separate set desander mud cleaner and a desilter mud cleaner is followed after the degasser. They work for the second and third stage separation. After desilter separator, most particles above 27 microns will be removed.
5)    As the desander, desilter can only remove particles bigger than 27 microns.  The smaller size is out of its working range. After some circulation, the fine solids contents will be higher and higher. The drilling mud will be too weight for drilling activities. A big bowl decanter centrifuge model GNLW452 is equipped after desilter to recovery the valuable barite and reduce the mud weight.
6)    Over 30 sets mud agitator and mud guns are equipped with the mud system for better mixing and to avoid the mud settle down.

The continuously low crude oil price for the past two years almost affected every company related to the oil and gas industry, especially the drilling companies and oil serve companies. Every economic unit is looking for a practical way to save the money while get the work done. And such trend brought some change when drilling companies or oil serve companies choose the equipment.

In oil and gas drilling practice, more and more drilling companies are using only 3 phase solids control equipment, including shale shaker, desander and desilter, for one thing, it could reduce the drilling companies’ cost if they don’t used the high cost decanter centrifuge, for another thing, the decanter centrifuge is more gentle for operating, only one set of decanter centrifuge may need 2 operators if it need to run around the hour. The drilling company tend to find a specialized mud company or mud station to do this job, for the forth phase separation.

Before, a mud station or mud plant is mostly used to storage the drilling mud, to get the new mud to be ready for new project, or just, to the most, add some necessary chemicals into the well treated mud. That’s why in traditional mind, the mud plant need mostly: 1. Mud tank, 2. Mud agitator, 3. Mud guns, 4. Jet mud mixing hoppers and shear pumps.

But since the change of equipment adoption in drilling companies, more functions are needed for the mud plant to have. Some mud plants now are using decanter centrifuge, it means, the forth phase of mud cleaning system is proceeded in a mud plant. In this way, the drilling companies are cutting the cost while the mud plant may gain more benefit from investing the high standard separation equipment.

Recently, GN has provided several high standard mud plant in this type, for more information, welcome to contact GN directly.
